The exchange was breached; the ledger kept producing blocks

The largest Bitcoin exchange of the day was broken into, while the Bitcoin network itself kept producing blocks, unaffected.

Why it happened

  1. 01账本由所有参与者各持一份,不存在单点。
  2. 02改写历史需要重做其后全部工作量,并且要比其余所有人加起来更快。
  3. 03交易所是账本之外的一层,它的失效不改变账本的状态。

Before · After

Before

Whether a ledger could resist attack with no administrator was only an argument.

After

The argument became a record. It also exposed, for the first time, that a secure ledger is not the same as secure user funds.

Why it matters

This was the first real test of the claim that no administrator was needed, and it passed.
